DECEMBER 4, 1909. INVENTORS' IDEAS. A MACHINE WITH 60 PLANES. THIS patent describes a flying machine in which the planes stretch between two rings, one inside the other, as shown in the drawing. The patent also covers the arrangement for suspending the motor in a ring, and also for adjusting the propeller-shaft. The arrangement of the inner member as shown is to allow space for the crew of the aeroplane, and across the bottom of the same member it is proposed that a platform should be fixed.—R. d'Equevilley-Montjustin. 17,370 of 1908. FEATHERING WINGS. IN this patent is described an arrangement for positively opening a series of louvres or vanes in a revolving wing and closing them auto- matically. The vanes in each wing are connected by a little crank to a rod, A, which is operated by the cam, C, so that they are opened when the wing is travelling upward, but when the wing commences to descend the vanes close automatically, assisted by a spring.'—Wm. Hammant. 23,129 of 1908. CANVAS PROPELLER. THIS invention relates to the construction of a propeller in which the blades are formed by canvas, silk, or similar material mounted on a frame, and consists in mounting the material loosely, so that when at rest the material is always baggy. The use of indiarubber or highly elastic material that will expand under pressure, and re- contract when the wind pressure is more gentle, is also covered.— T. Elliott. 9295 of 1909. A TANDEM MONOPLANE. THIS patent describes an arrangement of square monoplanes placed with the diagonal planes in a fore and aft direction, and arranged with a dihedral angle. The use of a keel, equal in area to the area of elevation of the inclined planes from which it depends, is claimed as an essential feature of this machine. The patent also describes the construction of a model apparatus for use as a toy.— W. F. Howard. 21,668 of 1908. BIRD-SHAPED AEROPLANES. THIS patent describes a design of monoplane founded on the experiments carried out by Mr. Jose Weiss with bird-shaped models. The special feature which is claimed in ihe invention is the use of a bump or marked convexity on the upper surface of the plane about its central or mid area and towards the front edge, sloping away to all parts of the wings with a particularly steep slope towards the front edge. The height of the bump must be ai least one-tenth of the distance from the front edge to the main beam which extends across the machine in front of the propellers.—Jose Weiss. 17,150 of 1908. ADJUSTING AREA OF PLANES. AN arrangement of planes in which the position and effective area of planes, especially of those for steering or controlling the machine, can be adjusted, is described in this patent. In the design shown, a square plane having an aperture is mounted in a frame, while below it another plane is SD arranged that it can be adjusted from one side of the central portion to the other, thus varying the effective area of the planes, and altering their relative positions.—J. L. Garsed. 23,316 of 1908. 779
